Danish government's latest report on antibiotics and farm animals(link will open PDF file)
This report examines how the Danish government's crackdown on antibiotics is affecting the use of drugs on the farms,
as well as bacterial resistance to leading antibiotics. The report shows that their
policies are generally working the way they had hopedbut not 100
percent. Farmers have cut their total use of antibiotics in animals by
almost two-thirds in recent years, although they're using bigger amounts of
specific drugs to treat sick animals. The report also shows that most major
kinds of bacteria are less resistant to leading antibiotics than they were a
few years ago, although the new policies haven't eliminated the problem: for
reasons that scientists can't explain, a few kinds of bacteria are actually
more resistant to certain antibiotics now than they used to be. Government
researchers say they expect it will take years to understand the full
effects of using antibioticsand restricting them.

The American drug industry's official report denouncing
the FDA(link will open PDF file)
This report denounces the FDA's on-going move to ban a popular antibiotic on chicken farms. The
FDA has proposed banning the chicken version of Ciprofloxacin
(fluoroquinolones) on the grounds that the most common form of "food
poisoning," Campylobacter, is becoming resistant to the drug because it's
used on farms across the country. The American Health Institute, which filed
this report, represents the major drug companies that make drugs for
agriculture.
